[Resolved] [Plugin: Multiple content blocks] Blocks not displaying

I am trying to get this plugin to work, and not having much success. I installed the plugin, and then in page.php I put the following:

<?php
/**
* The template for displaying all pages.
*
* This is the template that displays all pages by default.
* Please note that this is the WordPress construct of pages
* and that other ‘pages’ on your WordPress site will use a
* different template.
*
* @package WordPress
* @subpackage Twenty_Eleven
* @since Twenty Eleven 1.0
